Best solution for this problem

[Mat1asBEV&ICE]

Hello, the chassis harness manual says to drill a 1.25" hole for the main harness to pass through the firewall; last updated 2019. The Coyote Gen 3 fitment says a 1.5" hole; last updated 2023.

I drilled a 1.25" hole and there was no way the wires would pass through, especially at the Y junction. So I drilled a 1.5" hole, I barely got the wires through. Now I have this problem. What's the best remedy?

Sorry, not sure why the image is sideways. Thank you!

The solution is to replace the grommet with one that has a larger O.D.

Thank you, Jeff. Right after I posted I figured "gee, get a new grommet".

Looks like this one (https://www.mcmaster.com/2633N3/) will seal around the cables but it's only rated to 170F. Will that work?

Thank you.

Yes.
